PHP Warning: session_start()
0%
Description
Since the Update to v4.5.4 I get the following errors in the BE-Log:
Core: Error handler (BE): PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cache limiter - headers already sent in /typo3src/typo3_src-4.5.4/t3lib/class.t3lib_userauth.php line 256 Core: Error handler (BE): PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cookie - headers already sent in /typo3src/typo3_src-4.5.4/t3lib/class.t3lib_userauth.php line 256
I could not find out why these errors are comming, but they only exists in installations where the Scheduler is used and started by a cronjob. The Cronjobs are running every 30 minutes, so these messages are flooting the system log every 30mins.

First step: disable PHP warnings on production sites ;-)
Could you provide the calling line from your cron file? In CLI mode no headers are sent [1] so I guess you're invoking the scheduler in another way.
[1] PHP CLI mode

Hi Thorsten,
yes. You are right. We should disable the PHP warnings, but TYPO3 gets it before a user can see it :)
We use a managed server, the provider told us to invoke the scheduler this way:
Create a new bash-file which invokes the scheduler and start this file via the cronjob
The bash-file holds these two lines:
#!/bin/bash env -i /usr/local/bin/php5 -f /path/to/site/typo3/cli_dispatch.phpsh scheduler

Looks like it uses CLI, but to be sure could you please execute env -i /usr/local/bin/php5 -v on your server and post the result here?

So you're executing the CLI script using a CGI binary.
CGI is aimed to be used from a web server and TYPO3 acts like being run in a web server context.
You should ask your provider for a CLI PHP binary!

I think this could be closed.
The "bug" seems to be caused by a wrong configured system.

btw: whats the preferred way to disable PHP warnings? Via php.ini (display_errors = off) or via the TYPO3 Install Toll (increase [SYS][systemLogLevel] to 3 or higher)
Thanks for your support!
